kaypsmith Report post Posted April 24, 2020 Not seeing any info on your coach, we will need info on the coach to give a good answer, but if your coach has yellow turn signals on the rear, you probably will need to install the device that converts the wiring from five wire to four wire. Take a look at this site for more information, https://www.etrailer.com/question-123251.html. Share this post Link to post Share on other sites

Do you know if the Jeep has a CAN wiring system ? Some towing installations require the use of separate tow light harness or if there is room in the tail light fixture, others have installed bulbs and sockets inside the tail lights. Does your Coach have a relay / fuse box installed between the 7 pin socket and the main wiring harness for all the rear marker lights, turn signal and backup lights? CAN stands for closed area network. Even the light bulbs are special. Every function has an IP address. The same type system in now in the Newer Chassis wiring. The old days are gone. Simplicity has gone out the window. Rich. Note - your wiring pdf information link is https://www.blueox.com/wp-content/uploads/2015/07/BX88285.pdf Share this post Link to post Share on other sites
donaldrfiske Report post Posted April 27, 2020 2006 holiday rambler ambassador and wires go directly to hitch plug no box between plug and connection and problem fixed.... wiring harness was ground at frame on rear of Jeep so I ran another wire from battery ground on fire wall back to the harness ground and all lights work Share this post Link to post Share on other sites
dickandlois Report post Posted April 27, 2020 Donald, Thanks for update! Glad it was just as simple as adding a ground wire. Rich. Share this post Link to post Share on other sites
